Abstract

A sorption module for a sorption temperature-control device may include a housing enclosing a working chamber. A sorption zone and a phase change zone may be arranged in the working chamber where a working medium is displaceable reversibly between the sorption zone and the phase change zone. A sorption structure may be arranged in the sorption zone, and a phase change structure may be arranged in the phase change zone. An outer wall of the housing may include a double-walled section that may provide a cavity between an outer wall part and an inner wall part of the double-walled section, and the phase change zone may be arranged on an inner side of the inner wall part.

First claim

The invention claimed is:

a housing enclosing a working chamber and including a sorption zone and a phase change zone arranged in the working chamber where a working medium is displaceable reversibly between the sorption zone and the phase change zone;
a sorption structure arranged in the sorption zone and coupled to a sorption path in a heat-transmitting manner for guiding a sorption path medium;
a phase change structure arranged in the phase change zone and coupled to a phase change path in a heat-transmitting manner for guiding a phase change path medium;
an outer wall of the housing including a double-walled section arranged at least in a section to provide a cavity between an outer wall part and an inner wall part of the double-walled section;
wherein the phase change path is guided through the cavity, and the phase change zone is arranged on an inner side of the inner wall part; and
wherein the housing includes a jacket defining at least the double-walled section of the outer wall, the jacket including a supply connection disposed in the outer wall part for supplying the phase change path medium to the phase change path and a drain connection disposed in the outer wall part for draining the phase change path medium from the phase change path, the drain connection arranged spaced axially apart from the supply connection with respect to the longitudinal axis of the housing.

2. The sorption module according to claim 1 , wherein:
the sorption zone including the sorption structure arranged therein is enclosed by the phase change zone including the phase change structure arranged therein in a circumferential direction of a longitudinal axis defined by the housing;
the double-walled section of the outer wall defining the cavity is structured to enclose the phase change zone in the circumferential direction; and
the phase change zone is enclosed by the phase change path provided by the double-walled section in the circumferential direction.

3. The sorption module according to claim 1 , wherein the housing has a cylindrical shape and the jacket surrounds the phase change zone circumferentially to a longitudinal axis of the housing and extends axially to the longitudinal axis between two end bases disposed at axially opposite end faces of the working chamber.

4. The sorption module according to claim 1 , further comprising at least one spring element provided to pre-tension the phase change structure against the inner wall part of the double-walled section.

5. The sorption module according to claim 4 , wherein:
the at least one spring element is a spring strap wound in a circumferential direction of the housing around a longitudinal central axis of the housing in a helical manner; or
the at least one spring element is a spring plate bent in a circumferential direction of the housing about a longitudinal central axis of the housing.

6. The sorption module according to claim 4 , wherein the at least one spring element is disposed radially between the phase change structure and the sorption structure with respect to a longitudinal axis of the housing, and wherein the at least one spring element is perforated with a plurality of openings to provide a fluidic connection from the sorption zone to the phase change zone through the at least one spring element in a radial flow path.

7. The sorption module according claim 4 , wherein the at least one spring element is arranged radially between the sorption structure and the phase change structure with respect to a longitudinal axis of the housing, and wherein the phase change structure is configured as a capillary structure including a plurality of capillary structure packets pre-tensioned via the at least one spring element radially outwards against the inner side of the inner wall part of the double-walled section.

8. The sorption module according to claim 1 , wherein the phase change structure has a band shape and extends helically along the outer wall around a longitudinal central axis of the housing.

9. The sorption module according to claim 8 , wherein the phase change structure having the band-shape extends in plural turns along the outer wall about the longitudinal central axis, and wherein a gap is defined axially between adjacent turns and interrupts a capillary effect of the phase change structure oriented parallel to the longitudinal central axis.

10. The sorption module according to claim 1 , wherein the phase change structure includes a plurality of band-shaped strips extending in a circumferential direction of the housing, the plurality of band-shaped strips arranged adjacently along the outer wall in a longitudinal direction of the housing running parallel to a longitudinal central axis of the housing.

11. The sorption module according to claim 10 , wherein a gap is defined axially between adjacent band-shaped strips of the plurality of band-shaped strips that interrupts a capillary effect of the phase change structure oriented parallel to the longitudinal central axis of the housing.

12. The sorption module according to claim 1 , wherein the phase change structure includes a plurality of band-shaped strips extending parallel to a longitudinal central axis of the housing, the plurality of band-shaped strips arranged adjacently along the outer wall in a circumferential direction of the housing.

13. The sorption module according to claim 12 , wherein a gap is defined between adjacent band-shape strips of the plurality of band-shaped strips in the circumferential direction of the housing, the gap extending parallel to the longitudinal axis between adjacent band-shape strips of the plurality of band-shaped strips.

14. The sorption module according to claim 1 , wherein the sorption structure is a sorption material and the sorption path is provided by a plurality of tube bodies arranged in a tube block, and wherein the plurality of tube bodies are enclosed by the sorption material.

15. A sorption temperature-control device, comprising:
